Apply Text To Surface Question?
We lack some informations about your current file, but the basic way to do it is this one:


Unwrap your planks (Smart UV Project mode is good for this kind of object) and put your wood image texture on it with the following node organization:





In your picture software (Photoshop, Krita or even Blender), create your text with an alpha transparency.





Create a second UV Map and unwrap (Project From View mode) the front plank faces, those where the text is supposed to appear. You need this second UV Map because the first you've created won't fit.





Now you need to mix your wood Image Texture with your text Image Texture. Create a second Image Texture and load the text picture.  Into the Vector input, plug an Input > UVmap node, and choose the second UVmap you've created so that the text will be displayed according it. Use a Color > MixRGB node to mix the 2 Image Textures. In the Factor, plug the Alpha output of the text Image Texture so that it lets all the transparent area display the wood.





Of course it would need a bit more work, like creating a bump map and plugging it into your nodes Normal inputs to give your object a bit of 3D bumps...
